Abstract: A sheet discriminator, which can be included in an image forming apparatus, includes an optical information detector, a sheet distinguisher, and a sheet thickness detector. The optical information detector includes a light emitter to emit light to a recording medium and a light receiver to receive the light and detects information of the recording medium. The sheet distinguisher distinguishes a type of the recording medium based on the information detected by the optical information detector. The sheet thickness detector includes a displacement gauge to sandwich the recording medium with an opposing member disposed facing the displacement gauge and to move from an initial position thereof and a displacement detector to detect an amount of displacement of the displacement gauge. The sheet thickness detector detects a thickness of the recording medium based on detection results obtained by the displacement detector.

Abstract: In a board-to-board connector assembly, a plug-side power contact includes a first flat surface portion having a plate-like shape, a second flat surface portion having a plate-like shape and being opposed to a first part of the first flat surface portion and a power-contact-side connection portion connecting the first and second flat surface portions to each other. The first flat surface portion has the first part facing in parallel to the second flat surface portion and a second part or an upper end portion other than the first part. The first part includes a thinned portion having a shape recessed more deeply than a surface of the upper end portion and having a smaller thickness along the third direction than a thickness of the upper end portion.

Abstract: Disclosed is a connector mateable with a mating connector along a first direction. The connector comprises a housing and a plurality of terminals, wherein the housing includes a plurality of held portions, and the terminals correspond to the held portions, respectively. Each of the terminals includes a base portion, a first portion, a second portion and a third portion. The first portion extends directly from the base portion and is provided with a first contact portion which projects towards the second portion in a second direction perpendicular to the first direction. The second portion extends directly from the base portion and is provided with a second contact portion and a press-fitting projection. The second contact portion projects towards the first portion in the second direction and faces the first contact portion. The press-fitting projection projects towards the third portion in the second direction. The third portion extends directly from the base portion.

Abstract: A sheet discriminator includes a sheet loader on which a recording medium is loaded, an information detector to detect information of the recording medium loaded on the sheet loader, and a sheet distinguisher to distinguish a type of the recording medium based on the information detected by the information detector. The information detector detects the information of the recording medium with the recording medium being inserted between the sheet loader and the information detector. An image forming apparatus incorporates the sheet discriminator and an image forming part to form an image on the recording medium.

Abstract: In a cooling device that includes a cooling roller that comprises a hollow tubular member and a cooling medium transport unit for transporting a cooling liquid to the inside of the cooling roller and contacts a sheet-like member to cool down the paper, a turbulence generating unit that generates turbulence in a cooling liquid is disposed near an inner wall of the outer tube.

Abstract: A plug connector includes first contacts, a first housing comprising a guide portion and holding the first contacts, and a first metal member. The first metal member is attached to the guide portion and covers at least parts respectively of an upper surface of the guide portion and three outer surfaces of an end wall portion of the guide portion. A receptacle connector includes second contacts, a second housing holding the second contacts, and a second metal member. The second housing comprises a to-be-guided portion outside an arrangement range of the second contacts. The to-be-guided portion is adapted to be fitted to the guide portion and is formed by a U-shaped wall. The second metal member is attached to the to-be-guided portion and covers at least parts respectively of an upper surface of the to-be-guided portion and two inner surfaces of the U-shaped wall.

Abstract: A plug connector 1 includes a plug-side housing 5 and plug-side power supply contact 5A which is held by the plug-side housing 5 and in which a power supply current flows, the plug-side power supply contact 5A comprises at least a pair of integrally formed spring contact portions 15A and 15B each having a bent-plate shape, and the pair of contact portions 15A and 15B are provided so that their flat surfaces face each other.

Abstract: This connector is capable of engaging with a mating-side connector along the vertical direction. The connector is provided with a housing, a plurality of contacts, and a seal member. The housing has a top surface in the vertical direction, and an accommodation part recessed downward from the top surface. The contacts are held in the housing. The contacts are partially accommodated in the accommodation part. The seal member has a contact part and an accommodated part. The contact part is located on the top surface of the housing. The accommodated part extends from the contact part into the accommodation part. The accommodated part is held inside the accommodation part.

Abstract: An image forming apparatus includes an information obtainer, a memory, a candidate determining unit, and an image forming device. The information obtainer obtains feature information from the target recording medium. The memory stores at least one set of recording medium information regarding the target recording medium associated with the feature information and at least one set of image forming condition information corresponding to the recording medium information. The recording medium information is identification information. The candidate determining unit determines a candidate recording medium information from the recording medium information stored in the memory based on the feature information of the target recording medium obtained by the information obtainer. The image forming device forms an image on the target recording medium based on the image forming condition information in the memory according to the candidate recording medium information determined by the candidate determining unit.
